Abstract

The invention relates to agriculture, in particular to devices for feeding liquid fertilizers into the discharge line of sprinkler machines. The purpose of the invention is to increase productivity. The hydraulic device for the sprinkler for the sprinklers contains a tank for liquid fertilizers installed on the pressure pipe 1. The metering pump located across the pressure pipe 1 is in the form of an acceleration pipe 2 with a shock valve. The hollow bodies 3 and 4 of the shock valve are interconnected by a corrugated pipe 9. Irrigation water through the pressure pipe 1 is fed into the accelerating tube 2 and leaves alternately through one of the open outlet pipes 12 or 13. Liquid fertilizers through the liquid fertilizer feed pipe 10 enter the shock cavity valve. The impact valve under the action of water flow moves inside the dispersion tube 2. When the exhaust valves 7 or 8 interact with the stops 14 or 15 of the fertilizer, 8 irrigation water flows from the cavity of the impact valve. 1 il.

Description

The invention relates to agriculture, in particular to devices for supplying liquid fertilizers to the pressure pipe of sprinkler machines.

The purpose of the invention is to increase productivity.

The drawing shows a diagram of a hydraulic feeder.

The hydraulic feed loader for sprinkler machines contains a container for liquid fertilizers (not shown) installed on the pressure pipe 1, a metering pump made in the form of an acceleration tube 2 located across the pressure pipe 1.

In the booster tube 2, a shock valve is installed, which is made in the form of two hollow bodies 3 and 4 with check valves 5 and 6 and spring-loaded outlet valves 7 and 8. The hollow bodies 3 and 4 are interconnected by a corrugated pipe 9, and their cavity is in communication with a pipe 10 for supplying liquid fertilizers, in which the check valve 11 is located. At the outputs in the output pipes 12 and 13 of the booster tube 2, stops 14 and 15 are installed.

Hydraulic feed is as follows.

Irrigation water through the pressure pipe 1 is fed into the booster pipe 2 and then into one of the open outlet pipes 12 or 13, and liquid fertilizers through the pipe 10 for supplying liquid fertilizers enter the cavity of the shock valve. At this time, the exhaust valves 7 and 8 are in the closed state. Under the influence of water pressure, one of the hollow bodies 3 and 4 is carried away towards the open outlet pipe 12 or 13 and closes it. For example, the hollow body 3 closes the outlet pipe 12. The exhaust valve 7 is on the stop 14, which diverts it from its socket. In this case, the internal cavity of the housing 3 communicates with the outlet pipe 14 and liquid fertilizers under the influence of the created vacuum enter the irrigation water. When the outlet body 12 is slammed by the hollow body 3, the hollow body 4 from position A continues to move under the action of inertia to position B; while compressing the corrugated pipe 9, pressing the hollow body 3 against the output pipe 12. In the cavity of the shock valve, the pressure rises and the check valve 11 closes. By this time, the vacuum in the outlet 12 drops and the process of fertilizer entering the irrigation water slows down. With further compression by the hollow body 4 of the corrugated pipe 9, the fertilizers continue to flow into the irrigation water under pressure. The process of forced feeding of fertilizers into the irrigation water from the cavity of the housing 3 continues until the hollow housing 4 stops in position B. After the housing 4 stops in position B, it begins to move in the opposite direction under the influence of water flow to the outlet pipe 13 and the expanding force of the corrugated pipe 9. In this case, a vacuum is created in the cavities of the housings 3 and 4, under the action of which the check valves 5 and 6 are closed, and the valve 11 opens. As a result, fertilizer enters the cavity of the shock valve.

When the housing 4 reaches position A, the housing 3 moves away from the outlet pipe 12 and the exhaust valve 7, moving away from the stopper 14, closes. The housing 4, moving further from position A, already together with the housing 3 under the influence of inertia is carried away by the flow of water moving into the outlet pipe 13, and accelerates its movement. When the housing 4 reaches the B position, the stop 15 opens the exhaust valve 8 and the fertilizer under the action of the vacuum created at that moment in the outlet pipe 13 enters the irrigation water.

Further, the operation of the hydraulic feeder continues similarly to the above;
